From 1eb51d6a4fce66e7c4428b5761b75b357931422a Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Thu, 17 Sep 2020 14:44:36 +0100 Subject: nvmem: switch to simpler IDA interface We don't need to specify any ranges when allocating IDs so we can switch to ida_alloc() and ida_free() instead of the ida_simple_ counterparts. ida_simple_get(ida, 0, 0, gfp) is equivalent to ida_alloc_range(ida, 0, UINT_MAX, gfp) which is equivalent to ida_alloc(ida, gfp). Note: IDR will never actually allocate an ID larger than INT_MAX.
